Wireless Security

Wifi known as Wireless Fidelity allows a user to connect to the internet without using network cabling. Whether it’s from your bedroom, couch, indoors or outdoors data can be sent and received within the range of a wireless base station. Wifi uses 802.11a, 802.11b or 802.11g technologies to provide a very reliable connection that is also fast and secure.

Just as vendors prepare the first generation of dualmode cellular and WiFi mobiles for launch later this year, the wireless security community is starting to turn up threats to 802.11 VOIP handsets in the field. So how safe is VoIP on WIFI networks ?

For instance, independent security consultant Shawn Merdinger, who focuses on WiFi vulnerabilities, claims on the WV&E site that the UTStarcom phone is open to break-in from a hacker logging in remotely (a method known as rlogin). "Once an attacker has connected to the device through the rlogin service they have full access to the phone," says Merdinger.
